Method Detail
-
convert
protected abstract T convert(S sourceObject) throws X extends Exception
Deprecated.Converts a source type object to a target type object.
-
hasNext
public boolean hasNext() throws X extends ExceptionDeprecated.Checks whether the source type iteration contains more elements.
-
next
public T next() throws X extends Exception
Deprecated.Returns the next element from the source type iteration.- Returns:
- the next element in the iteration.
- Throws:
XNoSuchElementException- If all elements have been returned.IllegalStateException- If the iteration has been closed.X extends Exception
-
remove
public void remove() throws X extends ExceptionDeprecated.Calls remove() on the underlying Iteration.- Throws:
UnsupportedOperationException- If the wrapped Iteration does not support the remove operation.IllegalStateException- If the Iteration has been closed, or ifnext()has not yet been called, orremove()has already been called after the last call tonext().X extends Exception
-
handleClose
protected void handleClose() throws X extends ExceptionDeprecated.Closes this iteration as well as the wrapped iteration if it is aCloseableIteration.- Overrides:
